I am trying to test in app purchases in my application following plugin. Also I have checked this and thousands of other officical/not official articles but there is no result. I do not thins there is a problem in my code because I asked another developer to share me his code and I use it in my app. In his project this code works perfect but I have InAppBillingPurchaseException "Can not connect to Itunes Store". I also logged out of my real accounts before entering sandbox credentials. This is the code but the I do not think the problem is here:

public async Task<bool> PurchaseItemAsync()

    {

        var billing = CrossInAppBilling.Current;

        LastExceptionMessage = null;



        try

        {

            var connected = await billing.ConnectAsync();

            if (connected == false)

                return false;



            var purchase = await billing.PurchaseAsync(_kProductId, ItemType.InAppPurchase, _kPayload);



            if (purchase == null)

                return false;

            else if (purchase.State == PurchaseState.Purchased)

                return true;

        }

        catch (InAppBillingPurchaseException ex)

        {

            OnPurchaseException(ex);

        }

        catch (Exception ex)

        {

            //Dlog.Error("Issue connecting: " + ex);

            LastExceptionMessage = ex.Message;

        }

        finally

        {

            await billing.DisconnectAsync();

        }



        return false;

    }
